CHARLES WHITNEY, OF SYOAMORE, ILLINOIS.

GRAIN-BINDER.

FQPEGIFICATION forming part of Letters Patent No. 334,499, dated January 19, 1886.

Application filed December 12, 1883.

Serial No. 114,324. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES WHITNEY, a citizen of the United States, residing at Sycamore, in the county of De Kalb and State of This invention relates to improvements in grain-binding machines, and has for its ob- Io jects to provide simple and efficient means for actuatingthegraiircompressingdevice;to provide a compressing arm or finger having the required flexibility provided by the torsional action of the shalt by which it is carried; to

provide novel means for continuing the-compressing action on the grain after the binder arm has reached the limit of its advance movement; to provide means for increasing or diminishing the pressure of the compressing device on the grain being bound or as the binding material'is being tied. These objects I accomplishin the manner and by the means hereinafter described and claimed, reference being had to the accompanying drawings, in

which- I Figure 1 is an end elevation of sufflcient of a grain-binder to illustrate my invention, and

Fig. 2 a stubble side elevation of the same.

Fig. 3 is adetail showing wheel 10 and flange 16.

I have not deemed it essential to illustrate a harvesting-machine andits adjuncts, the packing mechanism, the cord-tying devices, or the clutch and clutch-dog for disengaging and holding the driving-gear out of action when the grain is being bound, as such features may be of any usual construction, but are preferably like those illustrated in the Letters Patent No. 306,082, issued October 2, 1884:, to Marsh and Whitney.

Referring to the drawings, the number 1 indicates the binder-arm rigidly fixed to the shaft 2 and provided with a rearward and downward heel project-ion, 3; and 4. indicates the compressing arm or finger rigidly mounted on a shaft, 5, which is capable of a torsional action to impart a degree of flexibility to said arm or finger. The driving-shaft 6 is provided with a driving-pinion, 7, for imparting'movement to the train of gearing, which consists of cogwheels 8, 9, and 10, mounted in suitablebearings on the frame. The binder-arm shaft 2 is provided with a crank-arm, 11, to which is pivoted one end of a link, 12, connected at its other end to a wrist-pin on the cog-wheel 9,

and the compressing-arm shaft 5 is provided with a crank-arm, 13, to which is pivotedone end of a link, 14,which is provided at its other end with a slot, 15, in which is arranged a wrist-pin on the cog-wheel 10, which latter is provided on its outer face with a projecting curved flange,'16, for engaging an anti-friction roller or stud, 17, on the link 14, for the purposes hereinafter explained.

In operation the pinion 7, being driven by the shaft 6, transmits motion to the cog-wheels in the directions indicated by the respective arrows, the wheel 9 operating the binder-arm through the link 12, crank arm 11, and shaft 2, while the wheel 10 actuates the compressing-finger through the link ll, crank-arm 13, and torsional shaft 5. \Vhen the requisite quantity of grain has been supplied to the binding-table to be bound and the binding mechanism is thrown into operation, as above stated, the binder-arm and compressing-finger advance toward each other, the binder-arm being rigid on its shaft, whilethe compressingfinger, although rigid on its shaft, is capable of yielding through the torsion of the shaft which carries it. The cog-wheel 9 having performed one-half of a revolution, the limit of the advance movement of the binder-arm will have been reached, and in order to continue the compression of the grain until the binderarm commences to recede the flange 16 passes over and in contact with the roller or stud 17 on the link 14, thus drawing the latter down ward and continuing the advance of the compressingfinger, and the consequent compression of the grain, until the cog-wheel 10 has traveled such distance as to cause its flange to leave the roller or stud, the slot 15 providing a space for the requisite travel of the wrist-pin on said cog-wheel while the connecting-link is held down by the flange. As here shown, this flange is eccentric to the axis of the cog-wheel 10, and in order to increase the compression of the grain I make the flange adjustable, so that one end may be adjusted inward toward the axis of the cog-wheel 10, as represented by the dotted lines 18, Fig. 1.

The manner of adjusting the flange may be varied; but a simple and useful means for effecting this result consists in providing a slot in the cog-wheel, in which is arranged a bolt having a nut and connected with the flange, as shown in Fig. 3.

The extension of stop3 on the binder-arm is provided, so that when the latter and the coinpressing-finger recede from each other incident to complete revolutions of the cog-wheels 9 and 10 such extension or stop will bear against or engage with the compressing-finger to hold it in position against the pressure of the iui'lowing grain. The pressure of the grain as itis being forced against the compressorfinger holds the train of gear steady by the pressure of the finger against the extension or stop 3, and at the same time preventing the rebounding and engaging of the clutch dog or pawl, which serves to dlsengage the train of gearing from the driving-shatt.

As before stated, I do not deem it essential to show this clutch, clutch dog or pawl, and their operating devices, as they may be and preferably are the same as illustrated in the patent before alluded to.

The dotted lines on the cog-wheel 10 show the varying positions of the connecting-link and the flange.

I do not confine myself to the torsion of the shaft for rendering the compressing finger flexible so as to yield, as other springs can be provided.

Having thus described my iuventi0n,what I claim isl. The combination,with the binding-arm 1,

the compressor-shaft 5, and the crank-arm 13,

rigidly secured to the latter, ofthe gear-wheel 10, having a wrist'pin and an eccentric flange projecting laterally from its face between its center and its toothed periphery, and a link,

14, having its upper end pivoted to the crankarm of the compressor-shaft, and its lower end loosely engaging the wrist-pin and provided with the roller or stud 17, substantially as described.

2. The combination of the gear-wheel 10, geared to the wheel 9,which operates the binder-arm, the wrist-pin, and the eccentric flange secured to the face of the wheel 10 between its toothed periphery and its center, the binderarin shaft connected with the wheel 9, the compressor-shaft5, the crank 13, rigid on the compressor-shaft, the link 14, pivoted at its upper end to the crank-arm of the compressor-shaft and at its lower end loosely engaging the wristpin on the gear-wheel 10, and the roller or stud 17 on thelink, substantially as described.

3. The combination of the gear-wheel 10, geared directly with the binder-arm-operating wheel and through it with the binder-driving shalt, the eccentric flange, and the wrist-pin secured to the wheel 10 between its center and toothed periphery, the torsional compressorshaft 5, the crank-arm 13, rigid on the torsional shaft, the link l-t, pivoted at its upper end to the crank-arm and loosely connected at its lower end with the wrist-pin, andt-he roller or stud 17, substantially as described.

4. The combination, with a compressing device and a link having a roller or stud. of an adjustable flange for increasing the compression of the grain while being bound, substantially as described.

In testimony whereof Ihave hereunto setiny hand in the presence of two subscribing witnesses.

C. \VHITNEY.
